%h2 here are: = @list.each |list| .row %span{:class => "id"}= list.id %span{:class => "name"}= list.name %span{:class => "telephone"}= list.telephone %span{:class => "actions"}= link_to "edit", edit_list_path(list) = link_to "new", new_list_path the html output getting is:
<html> <head> ... </head> <body style=""> <h1 class="heading">this lists</h1> <div class="wrap"> <h2>here are:</h2> <div class="row"> <span class="id">1</span> <span class="name">tom5</span> <span class="telephone">2357928154</span> <span class="actions"><a href="/lists/1/edit">edit</a></span> </div> <div class="row"> <span class="id">2</span> <span class="name">tom9</span> <span class="telephone">2345701247</span> <span class="actions"><a href="/lists/2/edit">edit</a></span> </div> <div class="row"> <span class="id">3</span> <span class="name">test3</span> <span class="telephone">235821421</span> <span class="actions"><a href="/lists/3/edit">edit</a></span> </div> [#<list id: 1, name: "tom5", telephone: 2357928154, created_at: "2013-09-03 14:58:22", updated_at: "2013-09-03 17:04:54">, #<list id: 2, name: "tom9 ", telephone: 2345701247, created_at: "2013-09-03 14:59:40", updated_at: "2013-09-03 17:05:00">, #<list id: 3, name: "test3", telephone: 235821421, created_at: "2013-09-03 15:27:11", updated_at: "2013-09-03 17:05:05">] <a href="/lists/new">new</a> </div> </body></html> i not sure if perhaps linus thing nitrous.io runs linux setup? if knows how can rid of hash @ end great!
your error in line:
= @list.each |list| equals evaluation , printing result (which in case object you're iterating over). if replace dash, evaluate expression want.
